Thanks Brian, love the detailed Replay recording!

While this is a certainly different from Chrome, I wonder how much we want to do (as Lexical) in this case. We have normalized editor behavior in the past to fix broken functionality around keypresses but in this case, the minimal behavior difference doesn't seem to impact functionality and works just like the built-in contenteditable.

Interestingly, different editors seem to have different behavior. GDoc has slightly different behavior from Quip (even though this specific case is normalized) and Notion didn't.

I'll check with the team to determime what our stance should be on this.
